Vision

A data cloud built with open metadata, open services, open sharing and standard formats.

This shifts the data focus so that:“What” is more important than “Where”. (the essence of a cloud)

Virtual Observatories (aggregators) are the interface to the cloud.

Guiding PrinciplesFor Science Information

SystemsA System with: Involvement of scientists in each stage of the process

Openly accessible data that are independently scientifically usable.

Every resource has a Universal Resource Identifier (URI).

Preserve all available knowledge about a resource. Provenance

Challenges

Robustness Its accessible and reliable.

Completeness Its the most definitive source of information.

Quality Assurance It can be trusted

Usability of Data FormatsOne click rendering and analysis

PreservationKeeping things safe for the future.

SeamlessEasily transition from data discovery to evaluation

to analysis to publication.

Meeting the Challenges

It takes effort to meet the challenges This is best met as a social effort (many people working

collectively)

Many of the challenges are being met by today’s virtual observatories in: Astronomy (IVOA)

Planetary (PDS)

Heliophysics (HPDE)

Earth Science ()

Further refinement and enhancements are happening now

Cross discipline usage and seamless integration remain a challenge to be met.
